<p>I noticed that some of CompileCodegenUnit's symbol_name dependencies don't have a deterministic order between runs on the same code. That is, they run in a different order. That's generally a bad thing for the query system if I understand correctly. Is this not a concern for CompileCodegenUnit for some reason? Or is this a bug?</p>
